Mark Hoppus has once again given an update on his cancer diagnosis.

The 49-year-old Blink-182 bassist and co-lead vocalist revealed that he has stage 4 diffuse large B-cell lymphoma, adding that his cancer is not related to bone, according to PEOPLE.

In a recording captured by the YouTube account Blink-182 Chile, Hoppus said, “My blood’s trying to kill me. My classification is diffuse large B-cell lymphoma Stage 4-A, which means, as I understand it, it’s entered four different parts of my body.”

“I don’t know how exactly they determine the four-part of it, but it’s entered enough parts of my body that I’m Stage 4, which I think is the highest that it goes. So, I’m Stage 4-A,” he explained.

Hoppus said he was diagnosed with the disease in late April. He has been undergoing chemotherapy treatments since then.

“If it [chemotherapy] is [working], I go back for at least three more rounds. Ideally, I go in tomorrow and they say, ‘Congratulations, your chemotherapy has worked and you’re all done and you’ll never have to think about this cancer again for the rest of your life,’” he added.

Hoppus also explained that if the treatments have not been working, he will likely have to pursue “other options,” such as a bone marrow transplant.

He told fans, “We’re beating this cancer. It’s just a matter of time.”

Hoppus went on to say that he has been leaning on his mother, who is a three-time cancer survivor. He said, “Oddly enough, we have the exact form of cancer. And she beat it, so I’ve been able to talk to her and bond with her quite a bit.”

“My mom has beaten cancer three times — twice for breast cancer and once for the same cancer that I have, which is diffuse large B-cell lymphoma,” he added.

Hoppus first revealed his cancer diagnosis on June 23. At the time, he said, he has “months of treatment ahead of me but I’m trying to remain hopeful and positive.”

“It sucks and I’m scared, and at the same time I’m blessed with incredible doctors and family and friends to get me through this,” he added.

Hoppus was asked about the side effects he has been having from chemotherapy. He said that he has been experiencing hair fall. He also said he occasionally has what he calls “chemo brain.”

“The first chemo, I felt like I was a zombie that fell onto an electric fence and was just being shocked,” the singer explained. “The second round of chemo, I just felt very weak and tired. Really just like the worst flu ever. The third round of chemo, I started retching. Nauseous and that whole thing.”
